Vm-bhyve sends it twice as this seemed to get Windows to respond to the request much more consistently and it would often appear to completely ignore a single kill command. I don't know why this is the case though or whether other hypervisors do something different when requesting a shutdown compared to what bhyve does. Simply triggering acpi poweroff "should" be enough.

I can just guess about this. When I press a power button on a desktop 
with Windows 10, it just ends screensaver (well, blank screen, to be 
precise), so I have to press it another time to actually turn it off. It 
does sound like a similar "issue".
